226 SUPPLEMENT. 
5 (a). Lycostomus rusticus. 
Ochraceus; abdomine, antennis (articulo basali excepto), tibiis tarsisque nigris; ore cum palpis fuscatis, pro- 
thorace lateribus leviter foliaceis, reflexis ; elytris postice subrotundato-ampliatis. Long. 16 millim. ¢. 
Hab. Muxico, Cordova (Hége). 
Easily distinguished from any species from Central America, except the following, by 
its ochraceous colour above; from Z. bucolicus it differs in having no tinge of black at 
- the apex of the elytra, in the body beneath and the tibie being black, and in the 
narrower thorax, with the sides much less foliaceous. The antenne have the basal 
joint only yellow. The prothorax has an obsolete channel, and is duller than in L. buco- 
licus; the coste of the elytra are less raised. 
A single specimen, of the sex of which I am not certain, but which from the mode- 
rately bent tibize I think to be a male, has occurred. 
5 (s). Lycostomus bucolicus, (Tab. XI. fig. 1,¢.) 
Ferrugineus vel ochraceus; antennis (articulis duobus basalibus exceptis), palpis, tarsis elytrorumque apice 
indeterminate nigris; prothoracis lateribus fortiter foliaceis, reflexis; elytris distincte quadricostatis. 
Long. 14-16 millim. ¢ 9. 
Var. Tibiis nigrescentibus. 
Hab. Panama, Tolé (Champion). 
The thorax in this species is rather wide and lunate, the front is bisinuate, sometimes 
appearing to have a double notch ; the centre of the disk has an obsolete channel, not 
reaching the front, where, indeed, there is a short carina. The antenne are black, but 
the two basal and the inner side of the third joint are yellow. The rostrum is rather 
long and thin, not differing in the sexes. The tibie of the males are moderately 
curved. The black at the apex of the elytra varies a little in extent, but is never much 
more than a spot undefined internally. Found very abundantly on the savannas near 
Tolé on a yellow-flowered composite shrub, about the flowers of which it may be seen 
flying in the hottest sun; large numbers were taken in copuld. ‘This species should 
precede L. loripes, Chev.

7 (a). Lycostomus sanguineus. 
Late sanguineo-rufus ; antennis, tarsis elytrorumque apicibus nigris; elytris intervallis subrugosis. Long.
